SPECIFICATION forming part of Letters Patent No. 693,263, dated February11,1902.

Application filed December 10, 1901. Serial No. 85,402. (No model.) v lTo all whomv t may concern,.-

Beit known that I, MAX GOLDBEEG, a citi' purpose of my improvement is t'provide a strong and effective joint-seat for pivoted parts, and theprecise improvement therein will be set out in the claims appendedhereto in connection with the accompanying drawings, in which- Figure 1isa top view of the shoe. Fig. 2 isa bottom View of the same. Fig. 3 isa section taken through theA joint-seat of the pivoted parts on thedotted line a. Fig. 4 is a cross-section of the pivoted parts on theline b looking at the joint-seat. Fig. 5 shows the joint-seat plate inperspective, wherein is seen'the supporting and holding parts for thepivoted ends of the shoe part-s. Fig. 6 is an end view of the joint-seatplate. Fig. 7 is a section of the same.

The pivoted shoe parts l l are provided with the usual heel-calks 2, andat its outer edge each part is formed with comparatively thin plates 3,which stand upward from the top of the shoe and when bent inward uponthe sides ofthe hoof form binders and give a firm hold thereon when theshoe is properly fitted to and clamped upon the hoof.

As a means of connecting and supporting the pivoted shoe parts I providea novel jointseat consisting ot' a plate 4, conforming to the 'curve ofthe toe end of the shoe and having on its under side Inediately of itslength an abutment 5, which stands across the plate and at each side ofwhich abutment the ends of the shoe .parts are seated and pivoted uponthe plate, so that the ends of the shoe parts abut against and aresupported by this jointplate abutment. For this purpose the proj ectionof this abutment 5 from theseat-forming surface of `this joint-plate isequal to the thickness of the pivoted ends of the shoe parts, and theabutment joins and stands inward from a vertical wall 6, which" projectsfrom the toe edge of the seat-plateand, together with the abutment,gives a firm walled support, as in Figs. 2, 5, and 6, to the pivotedends of the shoe parts and relieves the pivot-` forming set screws 7 ofundue `force and strain which would otherwise result from the suddenthrusts of the toe parts of the horses foot upon the ground. Thistoe-wall 6 of the joint-seat plate has also formed thereon a toecalk 8,the base of whichl underhangs the under side of the seat-forming surfaceof the plate and forms a recess or a space 9, into which the end of eachshoe part fits, as in Figs. 2 and 3, and gives a firm holding functionof the calk upon the ends of the shoe parts, thus relieving theirpivot-forming setscrews of wear and preventing any looseness between theends ofthe shoe parts and their seating-surface upon the joint-plate. Atits toe edge and mediately of its length the joint-'forming plate has abinder-clip 10, which is bent over and upon the front part of the hoof.This manner of constructing theiseatforming plate gives it the functionof a housing for the pivoted ends of the shoe parts, while it isrendered strong and stiff by the abutment 5, by the toe-wall 6 joiningthe abutment, by the calk 8 and the groove 9, and by the binder-clip 10standing up from the top of the joint-plate along itstoe edge.

Looking at Figs. 6 and 7 it is seen how the pivoted ends of the shoeparts are set within the recess 9, against the vertical side of theabutment 5, against the vertical wallG, and upon the shoulder 12 of thecalk which underhangs the under surface of the joint-plate, and it isthese housing parts that receive the full force of the tread of thehorse and relieve the pivoted end parts of m uch of this force.

Looking at Fig. 2 it will be noted that the toe-calk crosses the spacebetween the pivoted ends of the shoe parts, that the abutment closessaid space, and that the setscrews are on each side of said abutment andare spanned by the calk, so that the pivotscrews are within theprotecting functions of the calk and of the abutment.

A tightening screw-bolt ll connects the heel endsl of the shoe parts,the threaded end of the screw engaging one end of one ofthe shoe parts,so that when the shoe is properly set upon the hoof its binder-clips aredrawn tight around and upon the hoof by setting up the screw-bolt.

I claiml. In a horseshoe and in combination with clamping shoe parts, aseat-forming plate to which the shoe parts are pivoted, having asintegral parts an abutment standing cross- Wise mediately of the lengthof the plate, a Wall projecting from the toe edge of the plate crossingand joining said abutment, and a calk projecting from said abutment andWall, constructed and arranged to form a housing and support for thepivoted ends of the shoe parts, and means for binding the latter whenlll USG.

2. In a horseshoe and in combination with l clamping shoe parts, aseat-forming plate to which the shoe parts are pivoted, having anintegral vertical toe-Wall and a call; forming a shouldered recess toreceive and support the pivoted ends of the shoe parts, and means forbinding the latter when in use.

3. In a horseshoe and in combination with clamping shoe parts, aseatforming plate to which the shoe parts are pivoted, having asintegral parts an abutment, a toe-Wall crossing said abutment, a oalkforming an extension of the toe-Wall, these three parts comprising awalled housing and support for the pivoted ends of the shoe parts, and abinderplate forming an extension of the calk, and

means for binding the shoe parts when in use.

In testimony whereof I affix my signature in presence of two Witnesses.
